You can use wrestle specials with a spellbook and shield equipped, However I would recomend not having both since you won't be able to chug potions. On my wrestle mage I hold the faction order shield for it's HCI and DCI, and use a 50 EP ring with 15 HCI , 6 SDI and 3 FCR. That with other items i use Help me too hit more often with my disarms and para blows, and being able to chug saves my life all the time.
